Key and keyboard device

Abstract

A key is disclosed herein. The key is disposed on a baseplate of a keyboard device, and comprises a sheet metal keycap and a supporting structure. The sheet metal keycap includes a body portion and two bending portions. The two bending portions are formed by extending downward from a side of two punching holes on the body portion, respectively. The supporting structure is disposed between the sheet metal keycap and the baseplate. Two sides of the supporting structure are pivotally connected to the bending portions and the baseplate, respectively. The key is thinner due to sheet metal keycap which is integratedly formed. A keyboard device with a plurality keys is also provided herein.

What is claimed is: 
     
       1. A key disposed on a baseplate of a keyboard device, the key comprising:
 a sheet metal keycap including a body portion and two bending portions, wherein the body portion includes at least two punching holes corresponding to the bending portions, the at least two punching holes are disposed between an edge and a center of the body portion, and the two bending portions are extended downwardly from a side of the punching holes of the body portion, respectively; and 
 a supporting structure, disposed between the sheet metal keycap and the baseplate, and two sides of the supporting structure are pivotally connected to the bending portions and the baseplate, respectively. 
 
     
     
       2. The key according to  claim 1 , wherein the bending portions are formed by bending the body portion after the punching holes are formed. 
     
     
       3. The key according to  claim 1 , wherein the sheet metal keycap further includes:
 a film covering a surface of the body portion and the punching holes. 
 
     
     
       4. The key according to  claim 1 , wherein the supporting structure includes:
 a first support, wherein a side of the first support is pivotally connected to the bending portions, and another side of the first support is pivotally connected to a fixing portion of the baseplate; and 
 a second support, wherein a side of the second support is pivotally connected to the bending portions, another side of the second support is disposed in a slot of the baseplate, and a portion of the second support adjacent to a middle of the second support is pivotally connected to a portion of the first support adjacent to a middle of the first support. 
 
     
     
       5. The key according to  claim 4 , wherein when the sheet metal keycap is pressed, the sheet metal keycap moves downwardly in a straight line along a direction perpendicular to the baseplate, the first support and the sheet metal keycap are cooperated with each other and rotated via the pivot position, the second support and the sheet metal keycap are cooperated with each other and rotated via the pivot position and moves in a straight line along the slot. 
     
     
       6. The key according to  claim 1 , wherein the bending portions are a duckbill type, a double hook type, a double slot type or a double circle type. 
     
     
       7. The key according to  claim 1 , wherein the key further includes:
 a metal bar fixed to the bending portions. 
 
     
     
       8. A keyboard device, comprising:
 a baseplate, including a fixing portion and a slot, and 
 a plurality of keys disposed on the baseplate, the key includes: 
 a sheet metal keycap including a body portion and two bending portions, wherein the body portion includes at least two punching holes corresponding to the bending portions, the at least two punching holes are disposed between an edge and a center of the body portion, and the two bending portions are extended downwardly from a side of the punching holes of the body portion, respectively; and 
 a supporting structure, disposed between the sheet metal keycap and the baseplate, and two sides of the supporting structure are pivotally connected to the bending portions and the baseplate, respectively. 
 
     
     
       9. The keyboard device according to  claim 8 , wherein the bending portions are a duckbill type, a double hook type, a double slot type or a double circle type. 
     
     
       10. The keyboard device according to  claim 8 , further comprising:
 a metal bar fixed to the bending portions.
